High Speed Bullet Trains.
Germans Transrapid TR 09

A monorail technically which uses maglev technology and connects Sanghai to Pudong International Airport. It is the advanced design of TR08 with huge development and luxury and a latest invention which has maximum speed with minimum power consumption and least maintenance requirement. It has implemented a special measure to reduce the interior noise level in the train. It has excellent chair coach with utmost luxury and comfort a transrapid system does not allow any direct competition. It is so very well equipped with modern technologies that it can make passenger connections even in geographically challenged surrounding.Transrapid is a German high speed monorail train using magnetic levitation based on a 1934 patent. Planning for the Transrapid system started in 1969 with a test facility for the system in Emsland, Germany completed in 1987. In 1991, technical readiness for application was approved by the Deutsche Bundesbahn in cooperation with renowned universities.The super speed Transrapid maglev system has no wheels, no axles, no gear transmissions, no steel rails, and no overhead electrical pantographs. The maglev vehicles do not roll on wheels rather, they hover above the track guideway, using the attractive magnetic force between two linear arrays of electromagnetic coils one side of the coil on the vehicle, the other side in the track guideway, which function together as a magnetic dipole. During levitation and travelling operation, the Transrapid maglev vehicle floats on a frictionless magnetic cushion with no physical contact whatsoever with the track guideway. Onboard vehicle electronic systems measure the dipole gap distance 100,000 times per second to guarantee the clearance between the coils attached to the underside of the guideway and the magnetic portion of the vehicle wrapped around the guideway edges. With this precise, constantly updated electronic control, the dipole gap remains nominally constant at 10 millimetres. When levitated, the maglev vehicle has about 15 centimetres of clearance above the guideway surface.The Transrapid maglev system uses a synchronous longstator linear motor for both propulsion and braking. It works like a rotating electric motor whose stator is unrolled along the underside of the guideway, so that instead of producing torque it produces a linear force along its length. The electromagnets in the maglev vehicle that lift it also work as the equivalent of the excitation portion of this linear electric motor. Since the magnetic travelling field only works in one direction, if there were to be several maglev trains on a given track section, they would all travel in the same direction thereby reducing the possibility of collision between moving trains.
Compared to classical railway lines, Transrapid allows higher speeds and gradients with lower wear and tear and even lower energy consumption and maintenance needs. The Transrapid track is more flexible, and therefore more easily adapted to specific geographical circumstances than a classical train system. Cargo is restricted to a maximum payload of 15 tonnes (14.8 long tons; 16.5 short tons) per car. Transrapids allows maximum speeds of 550 km/h (342 mph), placing it between conventional High Speed Trains (200
